Mapei Polyethylene Waterproofing Tape, 50m, Used for Sealing Joints and Corners with Liquid Membranes

Key specs include a 50 mm width, a solid polyethylene backing, non-staining and odorless additives, high water resistance, run-resistance and abrasion-resistance, good adhesion to wood, concrete, tiles, metal and other wall coverings, and strong chemical resistance. It’s suitable for indoor and outdoor use and is easy to install without special tools.

It adheres well to wood, concrete, tiles, metal and other wall coverings, making it versatile for various sealing and waterproofing jobs on different substrates.

Use it for tiling waterproofing, sealing around fixtures, door frames, bathroom and kitchen surfaces, window areas, and other scenarios where a protective moisture barrier is beneficial.

Installation is straightforward: clean and dry the surface, cut the tape to the desired length, peel back the liner, apply the tape with even pressure, and press firmly to ensure a secure seal. Avoid stretching the tape and trim ends cleanly for a neat finish.

Both offer similar 50 mm width and waterproofing intent, but Mapeband PE100 may differ in formulation or performance characteristics. Check the PE100 product page for any variant-specific details and pick the one that best suits your substrate and environment. https://fepy.com/product/mapeband-pe100-rt-50ml

Mapeband PE150 is another variant with potentially different backing or formulation. While width is the same, performance characteristics can vary by product line. Review the PE150 page to choose the best option for your project. https://fepy.com/product/mapeband-pe150-rt-50ml

Yes. The tape is described as non-staining and odorless, designed for indoor and outdoor use, and provides a reliable seal without introducing harmful fumes, making it suitable for living areas when used as directed.

Store the tape in a cool, dry place away from direct sunlight and heat sources. Keep it in its original packaging until you’re ready to use it, and avoid exposing it to extreme temperatures or moisture before installation.

It combines durability (run- and abrasion-resistance), strong moisture and chemical resistance, broad substrate compatibility, and ease of installation, all while being affordable. These traits help deliver a reliable seal with cost efficiency on typical sealing projects.

Yes: ensure surfaces are clean and dry, cut clean edges, apply with even pressure along the full length, avoid air pockets, and overlap seams where needed. Allow sufficient curing or setting time for adjacent materials if required by your project.

The tape is designed for high water resistance and stability across temperature and humidity variations, providing a durable seal in both damp and dry environments, indoors and outdoors.
